PUMP.

Specification of Letters Patent.

Patented Aug. 26, 1919.

Application led May 9, 1918. Serial No. 233,507.

pump body is preferably placed near the lowest level of the liquid so that substantially all of the liquid may be lifted and `forced to a point suitable for use.

VOne object of the invention is to provide a pump body with open screened ends to permit the entrance of a liquid to the interior of the body.

Another object of the invention is to provide a pump body with a valve on one of its walls intermediate its ends.

Still another object of the invention is to provide valved pistons including piston rods for cooperating within the pump body and serving to move the liquid outward through a suitable outlet intermediate the ends of the pump body and in one of the walls thereof.

A further object of the invention is to provide levers suitably connected with the piston lrods and so arranged that a small movement of an operating rod will produce a large movement of the pistons, the plstons and levers beingy returned to their normal position by their properly proportioned counterweights, or springs.l

Broadly stated, the invention comprises a cylindrical pump body arranged for the free entrance of liquid therein, a valve and an outlet port therefor, a valved piston and a rod operable in the body, asystem of levers including a counter-weight for operating the rod and piston, a check valve in the outlet pipe, and an operating rod flexibly connected with the lever system and the counterweight for operating said levers.v

With these 'and other objects in view my invention consists in the novel details of construction and arrangement of parts which will be more clearly understood from the following specification and drawings.

The figure illustrated in the drawings is a vertical sectional view of the well having a horizontally disposed pump utilizing two pistons with certain portions of the connections being shown in elevation.

In carrying outl my invention a pump body 5a is horizontally arranged adjacent the bottom of the well. This pump body 5"L is provided with open ends that are closed by means of screens 50 and 51. This pump body 5"l is provided at one side with a circular depressed opening the walls of which are indicated at 52. Mounted in this depression and acting to close the opening is a valve 53. This valve may be hingedly attached as indicated at 54. Mounted to reciprocate within the pump body 5n are pistons C and D. These pistons may be composed of two disk like plates that may have clam )ed therebetween a leather cup-like washer. f ny usual means may be employed to retain the plates in position to clamp this washer in posit-ion. As shown the outer periphery of the washer lies in contact engagement with the inner surface of the walls of the pump body 5. The plates and washers are preferably provided centrally with a circular opening. To one side of one of the plates there is connected a flap valve that may be hingedly connected. This valve andthe hinged connection may be oi' any usual type of construction. These pistons C and D are also provided with the spaced members forming yokes for attachingl the piston rods 55 and 56 with the pistons.

The piston rod 55 also operates in a bearing 57 that is centrally disposed and supported in any usual manner. The piston rod 56 is slidable in the bearing 58 that is supported near the opposite end of the cylinder in any usual or customary manner. The bearings 57 and 58 serve as guide means to cause the piston rods 55 and 5G to travel in straight lines. The outer end ot' the piston rod 55 is pivotally connected with a lever 59, the pivotal connection being indicated at 60. The lever 59 is pivotally connected at 61 with a support 62. The pivotal connection is intermediate the ends of the lever 59.

The support G2 extends longitudinally in a plane parallel to the walls ot the pump body 5 and is secured thereon in any usual or customary manner. The other end of the lever 59 is pivotally connected at G3 with' a link (34. The other end of this link G-i is pivotally connected at G5 with an operating lever (S6. As shown the pivotal connection G5 'between the links G4 and the lever 66 is at the end oi the lever (36. This curved support 68.

This support 68 may be secured to theY outer surface of the pump body 5a. The upper end of thelever 66`is suitably connected with a flexible element 69. The lever 66 is provided with a portion indicated at 70 that extendsangularly to the major portion of thelever. The piston ro'd'56 has its outer end pivotally connectedat 71 with the lever 72. This lever is pivotally connected intermediate its ends as indicated at 7 3 with a support 74. Thisl support extends in a plane parallel to the Walls of the pump body 5a.

The other end of the lever 72 is pivotally connected at 75 with a link 76. This link 76 has its other end pivotally connected at 77 with -the operating lever 66. As shown the link 64 comprises a straight portion terminating Vin a portionV that is downwardly curved to connect with the lower end of the lever 66.v Thevlink 76 is reversibly curved and lies-above the support 68. This 'link is so curved that it will bev maintained out of contact with the support 68 when theoperating lever 66 is oscillated.V

Y The flexible element 69 whichmaybe wire cable has one of its ends attached to Y a counter-weight 78 and its other ends attached to the end of the' operating-'rod 7 9.

To provide foi` this latterk connectionl the' operating rod 7 9 is provided with alaterally extending lug` that maybe perforated ifndesired to provide for a more secure attachment ofthe element thereto. The flexible element 69, at one point, passes over a` guide pulley 80'that is carried at the lower endfof a suitable hanger 81 that may be secured to the underside of the well cover 82.

The element isV adapted to pass through a suitableantifriction device 83 softhat a portion of the element will travel in aV plane parallel to the operating rod 79. The antifrictiondevice 83 is preferably secured to the yoke 84 which also serves as a bearing and guide for the operating rod 79. As shown this operating rod 79 is positioned vertically and passes through the cover 82. To provide for better guiding and also to form a bearing a flanged bearing or floor plate 85 is mounted upon the'upper surface of the cover 82. The upper end of the rod 79 is provided with any enlarged portion 86 to provide means for exerting pressure.' on the rod 79 to move it down.

When pressure is placed upon this enlarged portion 86 the rod 79 movesV downward and pulls on the flexible element 69. This raises the'counter-weight 7 8, and moves theoperating lever 66, to the left. As this lever 66 moves to the left it forces the link 76 toward` the left, and the link 64 to the rightl As the link 76 moves to the left it forcesthe lever 72 to rotate around the pivot 7 3. and forces the piston rod 56 inward. This will cause the pistonD to movetoward 55 to move inward Vcarrying with it theV piston C. Thus it will be noted that both of the pistons move toward and from` each other simultaneously with the movement of the vertical travel of the operating rod 7 9 to which is connected the flexible element 69 and the counter-weight 78.

As the two pistons C and. D move toward each other the water trapped therebetween is forced upward through the outlet pipe 87 to the spout portion 88. The outlet pipe 87 may be secured to the walls of the pump body 5a in any suitable or customary manner. This outlet pipe` 87 isV also provided with a check valve 89. When the pressure is released fro-m the operatingrod 79 the counter-weight will cause the pistons to separate and their valves to open so that 'filled with very little friction. The valves `open toward each other so that when ,the

pistons move toward the center the valves w1ll tendvto close as soon as the water or liquid is compressed.

It will be noted Vfrom the manner of operating'the pump that just. as soon as the `pressure is released from theoperating rod 79 that the counter-weight-78 serves to return the pistons to their normal position ready to move for pumpingupon the ap` plication of pressure upon the operating rod 79.

The foregoing description and the drawings have reference to what may be considered the preferred, or approved form of my invention. It is to be understood that I may make such changes in construction and arrangement and combination of parts, materials,dimensions, etc., as may prove expedient and fall within the scope of the appended claims.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent is 1. A pump, which comprises a cylindrical body having a valve in one wall thereof, the ends of said body being screened, a plurality of valved pistons and rods operable within the body, Vand levers connected to the rods for moving the pistons in Vthev body, said body being provided with an outlet.
